Characteristic of such devices are their adaptability to facilitate use of as many subconductor cables as is required for each of the separate phases of the power transmitted. Conventional attachments to applicable structure of such devices allows further a proper disposition of the phased conductor bundles in a suitable arrangement for dependence from the suspension strings of power transmission line towers.

Cable support structures of the type disclosed herein have heretofore been used primarily as a carrier and spacer or spreader for power transmission lines having only three or four conductors whereof respective ones of three conductors carry the separate phases of the power transmitted, and a fourth conductor oridinarily functions as a messenger, or a catenary support wire. In a conventional form of this structure each conductor is secured in a separate clamping device by one or two bolts,-or preformed rods. Increasing the number of subconductor cables constituting a bundle in adaptions of prior arrangements renders them cumbersome, and possibly undesirable due to the multiplicity of bolt connections required that are subject to loosening from poor torquing or with time. Exemplary of a bolted clamp construction is the conductor spacer disclosed in US. Pat. No. 3,475,544, granted Oct. 28, 1969, to A. J. Reed. Typical of other prior art constructions are the arrangements disclosed in US. Pat. No. 2,928,636, issued Mar. 15, 1960, to A. T. Flower, in US. Pat. No. 3,005,609, issued Oct. 24, 1961, to E. J. Joffe, and US. Pat. No. 3,055,623, issued Sept. 25, 1962, to S. P. Becker. Each of these patented structures includes a pair of members within which conductor cables are secured in a requisite spatial relationship when these securing members are either pivoted or shifted with respect to each other to act as a clamp upon the cables when they are placed in generally conforming openings defined by specially formed portions of the members. However, these members usually have predetermined characteristic structural configurations necessitated by the particular utilization wherein they secure no more than three or four cables, and as a result their forms are generally restricted to the singular application for which they are fitted. On the other hand, a multiple conductor bundle according to the present invention has its basis in a uniquely adaptable configuration which is readily expandable for devices having utility in securing conductor bundles accommodating a large number of subconductors. Thus conductor bundles structured as disclosed herein are especially applicable to support the multiplicity of conductors that are used in implementing power supply in any one phase of ultrahigh voltage transmission.

Conventional limitations. upon the number of sub conductors that can be normally held by any individual support structure do not apply to the present invention where the circular shapes of all major securing components comprehend a teaching of extensive enlargements for accommodating subconductors in great'numbers. Moreover, individual conductor bundles of the embodiments of the invention disclosed herein have utility separately in the different phases of the electrical lines in that each bundle conductively ties together a number of phase related subconductors. In particular, separate subconductors are individually clamped in circumferencially distributed openings formed by portions of circular members made of electrically conductive material. A multiplicity of such circular structures have utility along the transmission line at predetermined distances from the supporting towers and at points thereat for suspending the line therefrom.

It is thus an object of the present invention to provide cable spacing and suspension supports for multiple conductor bundles of electrical transmission lines. 7

A further objective of the invention is to provide a cable support construction having applicability to conductor bundles of different multiplicities of subconductors.

These and other objects and advantages of the present invention will become more fully apparent from the following detailed description of the invention set forth herein and from the accompanying drawing made a part hereof in which:

FIG. 9 is a sectional view of part of the suspension yoke embodiment of FIG. 8, taken on line 9-9 therein, revealing details of keying and securing structure thereof.

The form of the present invention disclosed herein with reference to FIGS. 1 to 4 features a relatively large circular composite conductor spacer 10 which is characterized by an inner annulus 12 around whose outer periphery are positioned a set of prefabricated quadrants 14, 16, 18, and 20, forming a segmented collar about the annulus. These quadrants are retractable parts in a clamping arrangement provided for securing in spacer 10 a conductor bundle B so as to maintain the respective conductors Cof the bundle fastened at requisite locations about the spacer. As more fully appears in FIG. 1, the individual quadrants are alike with respect to their structural form, and each is made applicable in substantially the same manner to constrain a number of conductors C in the predisposed, spaced circular arrangement shown in the figure. A closer examination of quadrant 14, as exemplary of the other of such quadrants, makes evident a unitary construction 'therefor wherein a round pipe 22 curved approximately 90 degrees has been made integral with a correspondingly curved relatively narrow plate 24 by attachment, with welds or the like, between the curved outer peripheral edge of the plate and a curvilinear strip on a concaved surface of the pipe. Openings at the ends of pipe 22 are sealed by hemispherical caps 26 and 28 to provide the aforesaid clamping arrangement with components having a rigid construction made weather resistant by their continuous external surfaces. However, it should now also be obvious that the respective outer quadrants 14, 16, 18, and 20, can be produced as castings in a conventional manner which would permit a more steamlined integration of components than for the welded embodiment illustrated herein.

Quadrant 14 additionally carries a set of clevis connectors 30 and 32. Each such connector, as exemplified by the showing of connector 32 in FIG. 2, is in part constituted by a pair of short bars 34 and 36, which are maintained apart, facing in alignment, by attachment to the opposite sides of plate 24, by welds or the like, at separated areas of strength between the respective ends of the quadrant. Also as may be seen by reference to FIGS. 1 and 2, bars 34 and 36 of connector 32 are spaced in parallel, and extend radially past the inner peripheral edge of plate 24. The inner facing surfaces of the bars extensions are undercut slightly to provide a widened open passage 38 therebetween. Annulus 12 is essentially a unitary ring of plate material which is characterized by a generally uniform radial width, and an axial breadth closely approximating the breadth of quadrant plate 24. Thus connector passage 38, and a passage corresponding thereto defined by extended bars of connector 30 are suitably structured and disposed to receive therein cross-sectional portions of annulus 12 when quadrant 14 is properly placed for assembly to the annulus. The assembly is subsequently made fast by keepers, such as bolt or pin 40 shown in FIG. 2, which extend through axially aligned openings in the connector bar extensions and holes through annulus 12 disposed to mate with the aforesaid openings in the connector parts. Application of a suitable cotter pin 42 to secure bolt or pin 40 in the usual manner, is duplicated for all other such keepers.

Reference now to FIGS. 3 and 4 in connection with FIG. 1, discloses that each conductor C is retained at a predetermined location within the circularity of spacer by a fitting F. Each such fitting is a split structure including a first part made integral with annulus 12 in a generally semi-circular recess thereof, and a matching second part made integral with an associated quadrant in a corresponding generally semicircular recess thereof. These recesses are uniformly arrayed around annulus l2 within the outer peripheral edge thereof and the inner peripheral edges of quadrants l4, 16, 18, and 20, such that individual recesses of the annulus are paired respectively with quadrant recessesto form by alignment of their facing openings a circular array of split circular apertures A. Thus, a split structure of an exemplary fitting F which is accommodated in an aperture A appears in FIGS. 3 and 4 as having its matching parts symmetrically arranged in annulus l2 and quadrant 14, respectively. In the facing recesses of this aperture A are separately fitted generally semicylindrical, retainer shells 50 and 52, which when affixed in place, by welds or the like, constitute a split bearing collar 54. As'is more clearly shown in FIG. 4, collar 54 is placed so as to constitute raised ridges extending generally symmetrically from the planar surfaces of the 0pposite sides of annulus 12-and quadrant plate 24 when conformed in spacer l0. Bonded to the respective inner surfaces of retainer shells 50 and 52 are separable semicylindrical bushing halves 56 and 58 of a bearing sleeve 60 whose length matches that of its supporting collar 54. Sleeve 60 provides in a central passage 62 thereof a gripping surface which restrains a conductor C.

Electrically conductive materials are used throughout in the fabrication of spacer 10 so as to constitute conductors C maintained therein a conjoint conductive path for conductor bundle B. Aluminum plate, pipe, and bar are particularly suitable when used as indicated herein for the several structural elements of spacer 10, with the exceptions of the quadrant securing bolts or pins and cotter pins which are normally made of hardened galvanized steel and stainless steel, respectively, and the bushing halves of the conductor gripping bearing sleeves for which a thick conducting Neoprene is particularly appropriate. An exemplary form of such Neoprene has a DC. volume resistivity at 20C of not more than 600,000 ohm-cm, and a Durometer hardness of 60. As is evident from the disclosure so far, the structural arrangement exemplified by the embodiment of the invention shown in FIGS. 1 to 4 is most advantageously employed as a conductor spacer for multiple conductor bundles. Nevertheless, when insulation materials are used for the bearing fittings in one or several apertures of the aforesaid arrangement, so as to conductively isolate catenary cables or support rods which are made secure in such apertures, a broadly applicable conductor supporting spacer also becomes available in accordance with the present invention as shown in FIGS. 1 to 4.

Embodiments of the suspension yoke according-to the present invention, as they appear in FIGS. 5 to 9,

correspond to bundle spacer 10 to the extent that they I are all characterized by an assembly of circular and sectored components. However, the yokes disclosed herein are distinguished by a reinforcing construction, and further connective portions with which transmission line insulator suspending arms are adapted to be engaged. An arrangement for one such V-type suspension yoke appears in FIGS. 5 to 7 where a yoke is shown structured about an inner circular frame 72 having arms 74, 76, 78 and 80 which are uniformly disposed to radiate from a central mass thereof to a ringlike outer peripheral rim 82. This spatial disposition of the arms, which strengthens and adds rigidity to frame 72, also apportions this circular frame between succeeding ones of its arms into four sectors. Superposed on the rim section of each such sector is a quadrant member which functions in its connective association with frame 72 to retain within the peripheral edge of frame rim 82 four of the multiple conductors of bundle B, in amanner to be hereinafter more fully explained. Four rim sections 86, 88, 90 and 92 are shown in FIG. 5 as having assembled therewith quadrants 94, 96, 98 and 100, respectively. Referring particularly to the assembly at rim section 86, for an example of the arrangement at the other such sections, reveals that in the outer peripheral edge of section 86 are formed four uniformly spaced semicircular recesses 102, 104, 106, and 108. A similar arrangement of semicircular recesses 110, 112, 114 and 116, which are fashioned in the inner peripheral edge of associated quadrant 94, have openings therein adapted to confront correspondingly situated openings at the frame rim recesses when the quadrant is appropriately located by way of its attachment to rim section 86. The frame and quadrant recesses are by this means paired to obtain an alignment of their axial passages giving rise to a set of uniformly spaced parted apertures, each of which is adapted to securely maintain therein a conductor grip fitting to be hereinafter more fully explained.

Facilitating the requisite attachment of the quadrants separately to frame 72 are a circular array of clevis connectors which project radially toward a center from the inner peripheral edges of the respective quadrants. An assembly of the quadrants with frame 72 locates spaced portions of frame rim 82 within a circular array of passages provided by aligned channels fashioned by the paired legs of individual clevis connectors. Holes in these legs thus axially aligned with matching holes in rim 82 are equipped with headed bolts or pins which engage these mated holes, and are thereafter secured in position by cotter pins in a conventional manner. The clevis connectors applicable herein more particularly appear from reference to FIGS. 5, 6 and 7, illustrating the attachments for assembling quadrants 94 and 98 to their apposite sections of frame 72, which are exemplary of the other such attachments. Formed at the extended ends of quadrant 94 are radially disposed clevis connectors 120 and 122, respectively, which bracket further radial connectors 124, 126, and 128, uniformly spaced between them. As is evident from FIGS. 6 and 7, the quadrants have a semicircular outer ridge portion and generally flat parallel sides from which the paired legs of the clevis connectors project to overlap the parallel sides of frame rim 82. Thus, clevis connector 128, appearing in FIG. 6, provides legs 130 and 132 between which frame rim section 86 is pinned by a bolt 134, as was previously explained. To be seen in FIG. 7 is a clevis connector 136 at one extended end of quadrant 98. This end connector, which is exemplary of the other such end clevis connectors, provides slightly longer, partially rounded legs 138 and 140 forming a channel 142 in which frame rim section 90 is fastened by a bolt 144.

Exemplary of the aforementioned parted apertures which are formed when attachments between the quadrants and frame 72 are made so as to align recess passages in these members, is an aperture 150 arising from alignment of recesses 106 and 114 in frame rim section 86 and quadrant 94, respectively, as shown in FIGS. 5 and 6. Raised flanges or bosses which edge the respective rims of recesses 106 and 114 provide theipassages thereof with broadened bearing surfaces 152 and 154 for better maintaining in aperture 150 a conductor grip fitting 156, as was heretofore indicated. A preferred form of this fitting is a reinforced armored rod conductor grip such'as disclosed in U.S. Pat. No. 2,722,393, granted Nov. 1, 1955, to T. F. Peterson. As more fully illustrated in FIG. 6, fitting 156 includes a set of helically preformed rods, which when assembled on conductor C constitute a bulging sleeve 158 thereon, and a pair of semicylindrical bearing shoes 160 and 162 which are adapted to grip sleeve 158 and lock it to surfaces 152 and 154 when they are drawn together to form aperture 150. However, initially the gripped section of conductor C is enveloped by a pair of complementary protuberating semicylindrical sheaths 164 and 166, which have conductor accommodating recesses therein, and are adapted to underlie the rods forming sleeve 158 at the bulge thereof. These sheaths are advantageously made of the conductive Neoprene disclosed for use in the bearing sleeves of the FIGS. 1 to 4 embodiment herein wherefore they also constitute conductive links between the multiple conductors C by way of conductive material, such as aluminum, used for the major structural members of yoke 70. When bearing shoes and 162 have been drawn together, as in the assembly shown in FIG. 6, relieved portions centrally situated in the outer cylindrical surfaces thereof provide channels symmetrically disposed with respect to the parting line of the assembly in which bearing surfaces 152 and 154 of aperture 150 lie incontact with matching channel surfaces. Also as appears from the view in FIG. 6, the attachment of quadrant 94 to the recessed outer edge of frame rim section 86, when fitting 156 is positioned therebetween for coupling the conductor C it carries, effectuates a compression of the bulge in sleeve 158 between slightly flared, cylindrical surfaces of the central passage of the fitting which affords a measure of flexibility in the grip of conductor C by yoke 70.

The V-type suspension structure illustrated in FIG. 5 is arranged symmetrically about a vertical diametrical plane of circular conductor bundle yoke 70 to properly maintain this yoke within a transmission line by providing connections therefrom to a transmission line tower. This connective structure includes conformable linkages and 172 which attach inner frame 72 of the yoke to standard line insulator components 174 and 176, respectively, of the ball-and-socket type which is indicated in FIGS. 7 and 8, and more fully disclosed on pages 1215 and 1216 of the Standard Handbook for Electrical Engineers, edited by A. E. Knowlton, published by McGraw-Hill Book Co., Inc., New York, Ninth Edition (1957). As more fully appears from FIGS. 5 and 7, linkage 170 pivotally joins a clevis member depended from insulator component 174 to a tongue 182 which is an integral part of frame rim 82. More particularly, tongue 182 projects outwardly from frame 72 in line with radial arm 78 of the frame, and beyond the outer periphery of yoke 70 in traversing enlarged channels within clevis connectors at the facing ends of quadrants 96 and 98. Tongue 182 is in effect a bar-like suspension arm which is loosely received between legs 184 and 186 and socket-clevis member 180, and maintained dependent therefrom by a hexagonal bolt 188 whose shank extends through axially aligned holes in the legs and tongue. Bolt 188 is secured to clevis member 180 by a nut 190 and cotter pin in a conventional manner. As was previously indicated, linkage 172 is correspondingly constituted by a tongue 192, projecting from frame 72, which, by its connection within a socket-clevis member 194 depended from insulator component 176, functions as a further suspension arm for yoke 70.

The second embodiment of a V-type suspension structure according to the present invention is characterized by multiple attachments from each connective linkage of a multiple conductor bundle suspension yoke to transmission tower insulator components. In FIGS. 8 and 9 a yoke 200 of this embodiment is shown 7 as having an inner circular frame 202 including four evenly spaced radial arms 204, 206, 208 and 210, and quadrant members 212, 214, 216, and 218 arranged about the outer peripheral edge of the frame so as to complement the sectors defined between the aforesaid radial arms. An assembly of yoke 200 obtained by a circular distribution of clevis connectors therein operates to keep multiple conductors C of a conductor bundle secured in conductor grip fittings maintained within re- 1 cesses forming apertures of the yoke in effectively the same manner as that previously disclosed with respect to the first embodiment of the yoke appearing in FIGS. 5 to '7. However, only the form of quadrant 218 fully corresponds to the equivalent structure in the first embodiment, since for the requirements of the second embodiment, to be hereinafter more fully explained, quadrants 212 and 216 at one end and quadrant 214 at both ends have a configuration which is distinguishable from that of the aforesaid equivalent structure.

The connective structure by which yoke 200 depends from transmission tower insulators includes conformable linkages 220 and 222. As more fully appears from FIG. 9, wing-like appendages 224 and 226, of that part of linkage 220 that is integral with frame 202, project perpendicularly from the opposite side faces of the frames radial arm 208 and of its encircling rim 230. An ear-like brace 232 which is formed as an integral part of rim 230 so as to project outwardly from the rim in line with radial arm 208, serves as a retainer plate for quadrants 214 and 216 when they are secured thereto. Replacing the usual extended clevis connectors on the facing ends of quadrants 214 and 216 are reduced sections thereof which are circumferentially extended to form oppositely disposed, singular bar-like legs 234 and 236 on the respective quadrants. Thus, in the completed assembly of yoke 200 legs 234 and 236 have been positioned on the opposite sides of brace 232 where suitable holes in these legs are mated with a hole in brace 232 so as to define a passage through these parts to which a pin 238 is introduced and secured by a cotter pin. A dual suspension arrangement provided for linkage 220 includes a pair of socket-clevis members 240 and 242 which have the socket ends thereof joined to transmission line ball-and-socket insulators 246 and 248, respectively. Socket-clevis members 240 and 242 are situated, by a requisite disposition of the insulators .with which they are associated, where the bifurcated portions of such members overlie outlying portions 250 and 252 of appendages 224 and 226, respectively. Thus arranged, the socket-clevis members contain the aforesaid outlying portions loosely fitted therein, and an alignment of holes through these elements constitute passages wherein bolts are secured to provide requisite pivotal connections for suspending yoke 200. Exemplary of these connections is the attachment which FIGS. 8 and 9 shows wherein legs 254 and 256 of socket-clevis member 240 are maintained in overlapping relationship with portion 250 of appendage 224 by a bolt 258 secured by a nut 260 and a cotter pin. For a coordinated action with linkage 220 which maintains yoke 200 requisitely suspended from a power line transmission tower, the structural form and functional attributes of linkage 222 are fully mirrored in that which was previously disclosed as characterizing linkage 220. Accordingly, yoke 200 is suspended by connections to its frame 202 from a symmetrical arrangement of four insulator strings.

Other modifications and variations in the details of the present invention are possible in light of the disclosure herein. For example, the suspension yoke embodiments illustrated in FIGS. 5 and 8 are readily adapted to depend from a power transmission tower by employing conventional I suspension arrangements having singular connective linkages between the yoke frame rims thereof and the tower insulators. Thus, in the configuration of FIG.:5, the inner rim would be formed with only one radial tongue, and in the configuration of FIG. 8, this rim would be formed with a single'pair of appendages for their junctures to the insulators. In addition, the rim in the latter case would have a unitary retainer brace to coact with the facing ends of only two quadrants having singular circumferentially extended bar-like legs instead of radially oriented clevises. it is therefore to be understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described.
